Planning an RV Configurator with 100+ Components: Rules, Loading, and Updates

Define what you are counting

“100 components” can mean different things.

It might refer to catalogue entries, selectable accessories, individual model files, or objects inside a 3D scene. Those counts are not interchangeable.

A project brief should distinguish:

A large catalogue does not imply that every asset must be visible or loaded at once. Conversely, a short list of customer choices can still create complicated dependencies.

Write rules as explicit product relationships

Before building the interface, document what makes each selection valid.

An option record could include a stable identifier, supported models, model-year applicability, required options, conflicting options, and the visual assets associated with it.

Consider this illustrative example, which is not a specification for an actual CELA client product:

• A storage module requires a particular mounting kit.
• The module is unavailable with one seating layout.
• Changing to that layout therefore affects both the module selection and its representation.

The important decision is what the customer sees when that conflict occurs.

Should the interface block the layout change, ask permission to remove the module, or offer an alternative? Define that behavior with the manufacturer instead of leaving it to an incidental visual outcome.

Make the interface explain consequences

A disabled option is more useful when the customer can understand why it is unavailable.

“Requires mounting kit” provides a next step. “Unavailable with the selected seating layout” explains a conflict.

For consequential changes, show the proposed result before applying it. If switching layouts removes two selected accessories, the customer should be able to review that change.

The goal is to keep product decisions understandable without exposing internal part codes or engineering terminology unnecessarily.

Resolve the configuration before updating its representation

A useful design principle is to determine the valid product state first, then update the interface and visual representation from that result.

A proposed sequence is:

1. Receive the customer’s requested change.
2. Evaluate requirements and exclusions.
3. Request confirmation where the change has consequences.
4. Commit the valid selection.
5. Update controls and the associated visual content.
6. Update pricing or the enquiry summary where those features exist.

The exact implementation can vary. The acceptance requirement is consistency: the customer should not see one accessory selected in the interface and a different accessory on the vehicle.

Plan conditional loading around customer actions

For each asset, specify when it becomes necessary.

Some content is needed for the initial view. Other content may only become relevant after choosing a layout, opening an interior view, or selecting an accessory.

The loading plan should also describe what happens while content is arriving. Does the existing view remain visible? Is the selection marked as loading? What happens if the customer changes their mind before the asset is ready?

These questions belong in the interaction specification. Conditional loading should have predictable behavior, including when a request fails.

Make catalogue changes reviewable

Manufacturers update products over time. A material change and a compatibility change may require different kinds of work.

In CELA Technology’s ARKTO example, a supplier’s rooftop-fabric update was handled by changing the affected component without rebuilding the entire experience. That example is described on our Projects page.

For a new system, we recommend treating each catalogue update as a reviewable change:

• Identify the affected products and components.
• Check whether compatibility or pricing also changes.
• Review the updated visual representation.
• Test relevant saved configurations.
• Record the catalogue version used for release.

A component-only update still needs validation. Its smaller scope does not eliminate the need to check related behavior.

Test transitions as well as individual options

Opening every accessory once is not enough to test a configuration system.

Include sequences such as selecting an accessory and then changing to an incompatible layout; removing a required component; rapidly switching between alternatives; and restoring a saved configuration after a catalogue update.

For each sequence, check the selected options, visible components, explanatory messages, and any generated summary.

Where saved configurations are supported, define how discontinued or changed options are handled. An explicit explanation is preferable to silently substituting a different product.

Evaluate scale with evidence

Component count establishes scope. It does not establish responsiveness, reliability, or usability.

Ask a delivery team to demonstrate representative configurations and difficult transitions on the devices your buyers use. Performance reports should identify the tested version and conditions, while commercial claims should have their own supporting evidence.

For RV manufacturers preparing a brief, the most useful starting materials are an option catalogue, a compatibility table, examples of difficult combinations, and a description of how product updates are approved.
